Abstract
Accuracy of computational methods for tsunami kinematics is very important in obtaining reliable results. Methods based on Huygens principle are the most effective for computations on the rectangular computational grids. The present study proposes modification in the methodology of determining tsunami travel-times and of wave-ray paths. An approximate ray trace path can be developed from a source origin point to any other point on a computational grid by solving directly the problem – and thus obtain the tsunami travel times. The initial ray approximation can be optimized with the use of an algorithm that calculates all potential variations and applies corrections to travel-time values.

Key Words
ray path optimization, wave-ray, computational grid, wave travel time, tsunami wave kinematics
